摘要
为加快新品种青麦2号推广和成果转化应用,进一步完善标准化栽培技术,提高产品商品率,形成产业化,通过实施西宁市科技局农业成果转化资金项目“青麦2号示范与推广”,优化了适期早播、群体调优、配方施肥、病虫综合防治的技术核心,研制并集成青麦2号标准化栽培技术规程.青麦2号在3月25～31日播种,氮磷比1.0∶0.9,即N 120 kg/hm2、P2O5108 kg/hm2;播种密度450万～525万株/hm2其产量最高.
Abstract
To speed up the promotion and conversion applications of new varieties Qingmai 2,we further improved the standard cultivation techniques,improved product commodity rate,and formed industrialization through the implementation of Xining Municipal Science and Technology Bureau of Agricultural Achievements Transformation Fund Project "Qingmai 2 Demonstration and Promotion".Besides,we optimized the core technology of early seeding at appropriate period,population optimization,formula fertilization and pest and disease integrated control.Qingnai 2 standard technology procedures were developed and integrated.Results showed that Qingmai 2 was suitable for early sowing from 25 March to 31 March.Ratio of nitrogen to phosphorus was 1∶0.9.In other words,120 kg/hm2 N and 108 kg/hm2 P2O5 were the best formula fertilization program.Density yield from 4.5 million to 5.25 million plant / hm2 was the best.
